SHOVELlNG-BOARD FOR VEHICLES. c

SPECIFICATION forming part ofA Letters Patent No. 712,328, dated october28, 1902.

Application led April 14, 1902. Serial No. 102,944. (No model.)

To all whom t may concern.:

Beit known that we, JAMES A. PAXTON, residing at Ellsworth, and JOHN G.PAXTON, residing at Colfax, in the county of McLean and State ofIllinois, citizens of the United States, have invented certain new anduseful Improvements in Shoveling-Boards for Vehicles gand we do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the a'rt to which itappertains to make and use the same.

Our invention relatesY to improvements in shoveling-boards for vehicles.

The object of our invention is to provide a shoveling-board which willbe easy to manipulate and effective in operation.

It consists of guides fixed to the side pieces of the said board andmeans carried at the end of said guides for locking the board in aclosed or upright position.

It also consists in certain other novel constructions, as will behereinafter described and claimed.

In the drawings, Figure l is a fragmentary perspective view of the backend of a wagon, showing our improved shoveling-board applied thereto.Fig. 2 is an enlarged sectional view through a portion of the saine,parts being broken'away to more clearly show the form of the guide. Fig.3 is a detail view of the lock. Fig. 4is a section through the same.Fig. 5 is a section through the guide and its engaging pin.

Like numerals of reference indicate like parts throughout the severalviews.

Referring to the, drawings, the numeral l represents the bed of a wagon,2 the sides, and 3 our improved shoveling-board. The said board may beof any desired size; but we preferably give it such proportions as willfit the' back end of the wagon, as shown, the

height being equal to the height of the sideboards 2 and the lengthgreat enough to extend beyond the said side-boards and reachl to theouter face of a strengthening-strip 3a, which is secured to the end ofthe said board. Fitted around each end of the said board and screwed orotherwise securely fastened thereto are the side pieces or plates, as 4.We preferably construct these side pieces of sheet metal, although ofcourse any suitable material may be'used for this purpose. As eachdevice, as 13.

end of the base-plate 3 is provided with the same construction of sidepieces and guides,-

it is only7 necessary to describe in detail one of said ends with itscoworking parts. In order that this board might move on the desired arc,with its pivot-joint at the upper edge of the bed l, as at 3', and tohold vthe said board against displacement, we provide on the inner faceof the side plates the metallic segmental guide 5. This guide is soshaped and positioned that when the said' board is lowered to ahorizontal position the inner edge 6 thereof will be caused to rise atriiie above the upper surface of the bed l, so as to permit anunobstructed thrust of the shovel over the joint between the twoparts-that is to say, the path of the guide is not an arc of a perfectcircle, but that end which engages the guidepin 7 at thetime when theboard is in alowered or horizontal position is in operation aboutone-fourth of an inch nearer the point 6 than the opposite end thereof,the said diversion from the line of the perfect circle being greatest ata point marked 8 and gradually decreasing until it meetsthe said circle,as at 9. It is obvious that in order for the said guide-pin 7 which isstationary, to continue its travel in the groove 10 of the guide 5 it isnecessary for the said end 8 to be raised a distance equal to thediversion of the said guide from the said perfect circle, and in sodoing, the guide being riveted or otherwise securely fastened to theside plate 4 of the base-plate 3, the said board will be caused to risea distance equal to the variation of the aforesaid parts. To clearlyshow this difference we have shown in Fig; 2 of the'drawings a dottedline l1, which is an extension of the true circle struck frompivot-pointl 3. Any suitable brace or braces, as l2, may be employed tomore securely attach the end 8 to the extended lower corner of the sideplates 4.

In order to secure our board against accidental displacement after ithas been raised to a horizontal position, we provide at the opposite endof the guide 5 a suitable locking This locking device is circular Vinform and has a slot, as 14, extending from its outer periphery to thecenter thereof and in such a position as that when the handlel is turnedto its highest point the said'slot will register with the path of theguide. Thus it will be seen that when the board 3 is turned IOO to aperpendicular position the pin 7 will slide directly into the slot 14,whereupon it will only be necessary to turn down the handle 15, bringingthe solid wall 16 across the path and effectually preventing the fallingof the board. In order to give this locking member the proper throw-thatis to say, to bring the slot 14 in proper alinement with the path of theguide-we provide upon the outer face of the said member and around thehub of the handle a cut-out portion, as 17, which forms the abutments 1Sand 19, the former of which stops the upward movement of the handle 15when the slot 14 is in register with the path of the guide and thelatterarrests the downward movement of the said handle, presenting the solidwall16, as before mentioned. These shoulders 18 and 19 abut against thelug 19 formed integral with the guides. These locking members and guidesare preferably of malleable iron and may be secured in any suitablemanner to the side plates 4. An aperture to receiveitis formed in thesaid side plates and the whole mounted within the enlarged portion 2O ofthe guides.

It will be observed from the drawings that the guide-pin 7 is placed atthe strongest point possible--that is, through the side plates andcleats which are placed to receive the ordinary gate 21. This pin is inthe form of an ordinary bolt passing through the two members abovementioned and also through a separate plate 23, placed on the outside ofthe said side plates 2. An antifriction roller or washer 24 is providedbetween the head of said bolt and the outer face of the plate 23 andforms an enlarged head to travel in the path 10. It will be noted thatwe employT no hinges whatsoever aside from the guides, the pin slidingin the said guides forming all the pivot necessary.

In order to facilitate the easy removal of our board from engagementwith the pin 7,we provide near the end 8 a suitable recess or brokenoutportion, as 25, through which the said pin and roller may be slipped. Abridge, as 26, spans the said opening and forms a rigid connectionbetween the parts.

Although we have set forth one particular embodiment of thepresentimprovement, yet we do not desire to limit ourselves to the exactconstruction herein shown and described, but shall feel at liberty todeviate therefrom to any degree within the spirit and scope of ourinvention.

Any suitable means might be employed to retain the locking memberinposition, but we preferably employ the following: The aperture formed inthe guide 5 to receive the locking member is formed with a bushing, as5', to engage the space between the flanges 5 and 5* of the said lockingmember, and a countersink 5c is formed to receive one ofsaid Iianges.
